Suppose that it is known that 2% of the items produced by a particular machine are defective in some way, and that we will choose a random sample of exactly 15 parts made by this machine. a. What proportion of this machine's output is non-defective? b. What is the expected number of non-defective items, out of the 15 we select? c. What is the probability that exactly 14 of the 15 items is non-defective, GIVEN THAT more than 13 are non-defective?
